Tire head



FIG. 1 is a perspective view of a tire tread showing our new design, it being understood that the pattern is repeated uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a side elevational view thereof, the opposite side elevational view being identical thereto; and,

FIG. 4 is an enlarged fragmentary front view thereof.

In the drawings, the broken lines defining the tire inner bead and the peripheral boundary between the tire tread and the sidewall are for illustrative purposes only and form no part of the claimed design. 

The ornamental design for a tire tread as shown and described.
